According to Kyle Ringo of the Boulder Daily Camera, Colorado would play a nonconference football game at Ohio State in 2011 — If CU is able to begin a Pac-10 Conference schedule next year.

I asked CU associate athletic director David Plati and he would neither confirm nor deny Ringo’s report. Plati has scheduling responsibilities in addition to being the school’s sports info director.

Plati’s vague response probably means a game in Columbus is at least a possibility.

Said Plati: “Nothing is set in stone. We’ve discussed several options and have talked with more than one school. A few dominoes need to fall yet. Plus, we need to know if we’re in the Pac-10 (in 2011 instead of 2012) and have a nine-game conference schedule. And (even) if we’re still in the Big 12 in 2011, we have to replace the Nebraska game in Boulder since they’ll be in the Big Ten.”

As it stands now, Colorado is scheduled to host California as a non-conference opponent in 2011. Cal, obviously, is a member of the Pac-10. So, if CU were to be in that league next year the Buffs would need to find another opponent for the non-conference portion of the schedule — if the Pac-10 votes for an eight-game conference slate.

Ohio State’s 2011 nonconference schedule has home games against Akron and Toledo and a road game at Miami (Fla.), so the Buckeyes would need to add a game, assuming Big Ten members have eight conference games in the expanded 12-team Big Ten beginning next year.

BOULDER — Colorado coach Dan Hawkins confirmed Saturday morning after practice that tests revealed, as suspected, that sophomore safety Vince Ewing has suffered a season-ending tear of the anterior cruciate ligament (ACL) in his left knee during Thursday’s scrimmage.

Ewing, from Carlsbad, Calif., recorded nine tackles during the scrimmage before the injury, the second-highest total on the team behind true-freshman safety Terrel Smith’s 10. Ewing had come out of spring drills ranked second on the depth chart at strong safety behind starter Anthony Perkins. CU has not released an updated depth chart since August camp began.

There was some good news Saturday. Senior linebacker B.J. Beatty (leg) and sophomore defensive end Forrest West (knee) returned to full-speed drills. The morning session marked West’s first full practice of camp. The projected starter underwent surgery to repair a torn meniscus in late July.
